Abstract

The invention discloses a preparation method of a moisturizing and ash retaining cigarette paper. The preparation method of the moisturizing and ash retaining cigarette paper comprises the following steps of sequentially adding phosphoric acid and sodium dodecyl benzene sulfonate into calcium hydroxide solution, stirring for ageing, performing solid-liquid separation, and sintering obtained solid to obtain hydroxyl calcium phosphate; uniformly mixing an pulping calcium carbonate, the hydroxyl calcium phosphate and paper fiber to obtain a pulp; dehydrating, forming, squeezing and manufacturing the pulp into a wet paper matrix, adding additives into the paper matrix through sizing, and then performing drying, rolling and slitting processes to obtain the moisturizing and ash retaining cigarette paper. The prepared moisturizing and ash retaining cigarette paper achieves a certain moisturizing function and good ash retaining performance, improves smoking flavor of cigarettes and enhances the ash retaining property of the cigarettes during smoking.

Description

technical field [0001] The invention belongs to the technical field of cigarette processing, and in particular relates to a method for preparing moist-packed ash cigarette paper. Background technique [0002] With the advancement of tar reduction and harm reduction work in the tobacco industry, the tar content of cigarettes has gradually decreased, followed by the lack of aroma and increased dryness of cigarettes. In order to improve the sensory quality of cigarettes, while reducing tar and harm, the tobacco industry also takes flavor enhancement and moisturizing as one of the nine major projects in the medium and long-term scientific and technological development outline of the tobacco industry to carry out research. Nowadays, the research on increasing the flavor and moisturizing of cigarettes is mainly focused on the shredded tobacco or filter tip, which is reflected in the development of new flavor raw materials and research on humectants, that is, adding flavor raw mate...
